ABSTRACT
47 patients aged from 2 to 59 years affected by valvular congenital or mixed pulmonary stenosis including three fallot trilogies and one patient with right congestive cardiac failure are treated by percutaneous pulmonary valvulotomy between October 1986 and December 1990. All patients have been controlled with a mean follow-up of 6.5 +/- 1.1 years. The total gradient rate between pulmonary artery and right ventricule decrease from 112 +/- 55 mm Hg to 20 +/- 8 mm Hg on the last control with disappearance of infundibular inflammation and their auricular shunt in all the concerned cases. We observe the degression of right cardiac failure symptoms with disappearance of tricuspid insufficiency in the cases of advanced pulmonary stenosis with right ventricular dysfunction. Percutaneous pulmonary valvulotomie by its simplicity and inocuity, its long term efficiency is a good method of treatment of pure valvular or mixed pulmonary stenosis
